316Ti vs X2CrNiMoN25-7-4
Side-by-side chemical composition and mechanical property comparison.
Overview
316Ti
1.4571
Titanium-stabilized austenitic stainless steel with molybdenum. Stabilization prevents sensitization during prolonged high-temperature exposure. Very popular in Germany for chemical, pharmaceutical, and food processing. Being replaced internationally by 316L (1.4404) for most applications.
X2CrNiMoN25-7-4
1.4410
Super duplex stainless steel (SAF 2507 / UNS S32750) with 25% Cr, 7% Ni, 4% Mo, and high N for PREN ≥42. The highest corrosion resistance and strength among standard duplex grades — YS ≥550 MPa is ~2.5× that of 316L. Service temperature up to 300°C. Used for subsea oil & gas equipment (manifolds, trees, risers), desalination plants, flue gas cleaning, chemical tankers, and mining equipment in severe chloride environments. Requires careful welding to avoid sigma phase.
